To mZZ whom it may concern:

Be it known that I, A. BERrsnLL IRELAND, of Greene, in the county ofUhenango, in the State of New York, have invented new and usefulImprovements in (lasein-h'iangling Machines, of which the following,taken in connection with the accompanying drawings, is a- 1 full, clear,and exact description.

This invention relates to improvements in machines for mangling caseinor curd.

cakes of varying quantities or weight and is usually very tough andrubber-like, so that it is very difticult to disintegrate or mangle.

The object of my present invention is to enable the casein cakes to bequickly and easily shredded or disintegrated into small irregularparticles. This is accomplished by means of a rotary mangler and asliding toothed bar, movable back and forth and across in closeproximity to the periphery of the rotary mangler.

Other more specific objects and uses will be brought out in thefollowing description.

In the drawings, Figures 1 and 2 are respectively a top plan and an endview of my improved mangling-machine. Figs. 3 and a are sectional viewstaken, respectively,on lines 3 3, Fig. 1, andi a, Fig. 3. Fig. 5 is aplan of the developed surface of the cylinder or rotary mangle, portionsthereof being broken away, so as to show several rows of mangling-teeth, this View also showing the position of the teeth of thesliding bar.

Similar reference characters indicate corresponding parts in all theviews.

A suitable rectangular supporting frame or base is provided andpreferably consists of front, rear, and end walls 1, 2, and 3, which areunited to each other to form a rigid open frame or bed, the end walls 3being provided with suitable bearings at, in which is journaled a rotaryshaft 5, having a driving-pulley 6 at one end and a cam 7 on itsopposite end. Mounted upon and secured to the intermediate portion ofthe shaft is a rotary 3 mangling-cylinder 8, which revolves in theopening in the supporting-frame and is provided with a plurality ofpairs of parallel rows of mangling-teeth 9 upon its periphery. I

have shown four pairs or sets of these teeth,

such sets or pairs being designated by the letters u, b, (x, and (Z, andeach set is composed of two parallel rows arranged closelytogether,

This 1 casein or curd is made from the residue of 5 milk after the creamhas been separated there- E from and usually consists ofirregular-shaped i l but spaced apart circumferentially, and the 2 teethof each row are also spaced apart axially of the cylinder. These teeth 9consistof the square heads of suitable bolts which are passed throughthe shell of the cylinder and are held in place by clamping-nuts on theinner ends of the bolts, as best seen in Fig. 3. A sliding bar 10 ofsuitable material, as wood, is guided in suitable openings or guides 11in the end walls 3 beneath but slightly in front of the cylinder 8 andis inclined transversely and tangentially to the periphery of thecylinder and is provided with a row of manglingi teeth 12, which arealso square and form the heads of suitable bolts, which are passedthrough the bar 10 and clamped on its under side by nuts 13. The upperface of this bar 10, adjacent to the periphery of the cylinder 8, isprovided with a metal wearing-plate 14, which is held in place bysuitable grooves and may be removed when worn and replaced with anotherplate without removing the bar 10. The teeth 12 are also spaced apart asuflicient distance to permit the teeth 9 to pass through the spacesbetween the teeth 12. The cam 7 upon the shaft 5 is provided with anannular bearing which is disposed in a plane at an angle other than aright angle with the axis of the shaft 5 and rides between and engagesthe adjacent faces of a pair of antifriction-rollers 15 on the adjacentend of the bar l l l l l i l duces a reciprocal motion of said bar 10back and forth across the face or periphery of the cylinder 8 parallelwith the axis of said cylinder.

It is apparent from the construction of the cam that during one-half ofits revolution the bar 10 will be moved continuously in one direction acertain distance and during the other half of the revolution an equaldistance, so that the maximum throw or movement of the cam-in thisinstance one inch is always uniform and continuous from one extreme tothe other, and in view of the fact that this bar and the teeth 12thereon are moved back and 4 forth in the manner described it isnecessary to have the teeth 9 of diametrically opposite sets, as thesets 7) and (Z, twisted at a slight angle, or, rather, arranged toconform to the position of different points of the cam during itsrevolution, as indicated by the line K, Fig. 5, in which it will be seenthat certain points of the cam stand at substantially right angles tothe bar 10, while other points are disposed at an angle with said bar,and therefore it be- 10, whereby the rotation of the cam 7 pro-' comesnecessary to dispose the heads or teeth 9 in spiral rowscircumferentially around the periphery of the drum or cylinder, so thatthe teeth 9 may always pass between the teeth 12 without friction orclashing with the latter teeth during the reciprocal movement of the bar10. It is also evident by this peculiar arrangement of teeth on thecylinder and sliding bar and the reciprocal motion of the bar the curdwill be cut by one set of teeth at one point, while the next set willcut at a different point, where the former teeth left off, and each setwill tear through the curd at different points, thereby traversing theentire body of the curd and insuring a complete disintegration of thecakes a little at a time, but continuously, until the whole cake is torninto particles, this action of the mangling-teeth being produced withcomparatively small power on account of the small resistance andshearing effect of the teeth with each other and with the body of thecurd.

I have previously stated that the bar 10 was supported in an inclinedposition transversely at the lower front side of the cylinder 8, anddirectly in front of the cylinder and bar 10 is an inclined table 16,which is disposed in substantially the same plane as the upper surfaceof the bar 10 and is provided with a series of V-shaped ribs 17 on itsupper face, which serve to guide the body of curd and to permit it tofeed by gravity between the cylinder 8 and bar 10. This table is alsoprovided with side walls 17 to keep the curd within the bounds of themangling-cylinder 8 and bar 10, the outer or upper end of the tablebeing adjustably secured to suitable brackets 18, rising from thesupporting bed or frame and provided with suitable slots 19 forreceiving clamping-bolts 20, these clampingbolts being passed throughthe sides 17' for securing the table in its adjusted position, the lowerend of said table being adjustable by a suitable screw 21, as best seenin Fig. 3.

1n the operation of my invention the body of the casein or cake of curdis placed by hand upon the inclined table 16, along which it gravitatesor may be fed by hand between the cylinder 8 and the upper face of thebar 10, where it is caught by the revolving teeth 9 and sheared againstthe teeth 12, thus removing or tearing small particles of the curd. fromthe main body as each row of teeth 9 is successively presented to theteeth 12, or rather as the teeth of each row pass between the teeth 12.The movement of the bar 10'is governed by the cam 7, and therefore byarranging the teeth 9 circumferentially around the cylinder in a planeparallel with the cam it is evident that by rotating the cam andcylinder together the movement of the bar 10 is timed so that the spacesbetween its teeth will be brought into position to permit the teeth 9 ofeach row to pass successively between the teeth 12, thus traversing andcutting the entire body of curd as it is fed between themangling-cylinder 8 and bar 10. This will be better understood uponreference to Fig. 5, in which I have shown the teeth of the bar 10 infour different positions to which it is brought by the cam 7 during onecomplete rotation of the cylinder and cam, these positions being assumedas each set a, 6, c, and (Z of the teeth 9 are successively brought intoregistration with the teeth 12 of the bar 10. In this Fig. 5 in thefirst row (marked a) the teeth 12 are indicated in the extreme positionto the left as effected by one position of the cam 7. Now when the camis rotated a quarter of a turn or the distance between one set of teethand the next succeeding set, as from a to 7), the bar 10 will have beenmoved one-half inch, providing the cam has an inch throw, or to theposition seen at b, Fig. 5. In the position seen at a one row of thatset has just passed between the teeth 12 and the other row is just aboutto pass between the said teeth 12, and at this point the cam standsnearly at right angles to the bar, while at the position 6, Fig. 5, thecam stands at an angle and the teeth 9 of the set 6 are thereforedisposed at an angle. As the set 0 is brought to the teeth 12 the barwill at this time have moved to its extreme position to the right, andthe teeth of the set 0 are therefore arranged to pass between the teeth12 of the bar when in this position. gins to return the bar to its firstposition, and when the set (Z of the teeth 9 are brought intoregistration with the teeth of the bar 10 the cam 7 will have drawn saidbar back one-half of its movement, so that when the complete revolutionof the cylinder and cam is made by the return of the set a of teeth, asseen at the bottom of Fig. 5, the cam will have returned the bar 10 andits teeth to the starting position.

It will be observed upon reference to line as, Fig. 5, which is thedeveloped line of one circumferential row of teeth 9 and also thedeveloped line of all points in the cam that the points in line oppositeto the sets of teeth marked 5 and d are at an angle with the axis ofrevolution of the cam and cylinder, while the extreme points at a and care perpendicular to the axis and bar 10, and therefore the teeth of thesets a and c are arranged parallel with the line of rotation, while theteeth of the sets 7) and d are disposed at an angle with the line ofrotation.

It is believed that this description is sufficiently clear to enable anyone skilled in the art to make and construct this machine.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
